This package allows to simulate Post-Keynesian Stock-Flow Consistent Models, following the approach of Godley, W. and M. Lavoie, 2007: Monetary Economics An Integrated Approach to Credit, Money, Income, Production and Wealth. Palgrave MacMillan, New York. The package uses the Gauss-Seidel algorithm to solve linear systems of equations, following the approach found in Kinsella, Stephen and O’Shea, Terence, Solution and Simulation of Large Stock Flow Consistent Monetary Production Models Via the Gauss Seidel Algorithm (December 21, 2010).

The paper surveys the recent literature on the fiscal implications of central bank balance sheets, with a special focus on political economy issues. It then presents the results of simulations that describe the effects of different scenarios for the Federal Reserve’s longer-run balance sheet on its earnings remittances to the U.S. Treasury and, more broadly, on the government’s overall fiscal position. We find that reducing longer-run reserve balances from $2.3 trillion (roughly the current amount) to $1 trillion reduces the likelihood of posting a quarterly net loss in the future from 30 percent to under 5 percent. Further reducing longer-run reserve balances from $1 trillion to pre-crisis levels has little effect on the likelihood of net losses.

Welcome to INFO-201, Technical Foundations of Informatics. This is a course at the University of Washington’s Information School, and these materials were co-developed by Michael Freeman and Joel Ross. The purpose of this course is to teach students the necessary technical skills to begin writing code to work with data. While these resources are built for students currently enrolled in the course, they have been structured to be an online resource for anyone hoping to learn to work with information using programmatic approaches.

In this paper we show that a rational consumer choice along the lines traditionally suggested might lead to paradoxical results if one considers multidimensional goods, which incorporate a series of incommensurable aspects. Thereby, we explore the similarity between the resulting paradox and Kenneth Arrow’s well known Impossibility Theorem. Based on these considerations we suggest a solution for the former problem along the lines of Herbert Simon and Amos Tversky, which might—if driven to its extreme—even provide a unique and arguably rational solution for consumer choice among multidimensional goods. Eventually, we argue that the resulting framework poses a potentially useful starting point for further developing an evolutionary theory of consumer choice.

Building on Thompson’s (1967) typology of long-linked, intensive, and mediating technologies, this paper explores the idea that the value chain, the value shop, and the value network are three distinct generic value configuration models required to understand and analyze firm-level value creation logic across a broad range of industries and firms. While the long-linked technology delivers value by transforming inputs into products, the intensive technology delivers value by resolving unique customer problems, and the mediating technology delivers value by enabling direct and indirect exchanges between customers. With the identification of alternative value creation technologies, value chain analysis is both sharpened and generalized into what we propose as a value configuration analysis approach to the diagnosis of competitive advantage. With the long-linked technology and the corresponding value chain configuration model as benchmark, the paper reviews the distinctive logic and develops models of the value shop and the value network in terms of primary activity categories, drivers of cost and value, and strategic positioning options.
